Try this script.
It reloads the document when NS4 is resized
<script language="JavaScript">
function reloadPage(init) {
if (init==true)
with (navigator) {
if ((appName=="Netscape")&&(parseInt(appVersion)==4)) {
document.W=innerWidth;
document.H=innerHeight;
onresize=reloadPage;
}
} else if (innerWidth!=document.W || innerHeight!=document.H) {
location.reload();
}
}
reloadPage(true);
</script>
Hope this works in your case.
